Why is location mandatory on an invoice?

AI generated answer (using internal Slack threads):

The Location field is mandatory on an invoice because it is used to track inventory. If you have the multi-inventory location feature enabled in NetSuite, locations become mandatory in bills, invoices, and other inventory-affecting transactions. This is because NetSuite needs to know where the inventory is coming from for each transaction. Additionally, the Location field could also be made mandatory due to a workflow or script. For example, a company might have a workflow where the Location field is automatically filled with a default location when a bill is saved. Please note that you cannot make the Location field optional through the customize form feature. This is because a standalone bill is inventory affecting, and thus, the Location field is required.
